1.Particle size: Powdered organic fertilizers have smaller particles, usually in powder form, while granular organic fertilizers are formed by granulating powder into granules. The particle size of granular organic fertilizers is relatively large and the shape is regular.

 

2.Application method: Powder organic fertilizers are usually suitable for uniform spreading or spraying, and are usually applied manually. Granular organic fertilizers are more suitable for mechanical application, such as fertilizing machines, seeders, etc. The regular shape and larger particle size of granular organic fertilizers make them easier to control and quantify during application.

3.Applicable situation: Powder organic fertilizers are suitable for small-scale application, mixing with soil before sowing, or using as base fertilizers. Granular organic fertilizers are suitable for large-scale application, mechanical fertilization, and long-term fertilization.

 

 

4.Nutrient release rate: Due to the small particles and large surface area of powdered organic fertilizers, the nutrient release rate is fast, which can quickly supply the nutrients needed by plants. However, granular organic fertilizers have relatively slow nutrient release rates due to their larger particles, and require gradual decomposition and transformation in the soil before they can be supplied to plants.

5.Storage and transportation: Powder organic fertilizers are relatively sensitive during storage and transportation, and are prone to drifting, moisture, or clumping. Granular organic fertilizers have good flowability and packaging stability due to their regular particle shape, making them easier to store and transport.

 

 

In summary, although granular organic fertilizers have certain advantages in application methods and applicability, from the perspective of maintaining organic composition and effectiveness, powdered organic fertilizers are more ideal. Therefore, if the goal is to maximize the retention and utilization of organic fertilizers, powdered organic fertilizers are a better choice. ‌
